BOTTLE-STOPPER FASTENER.

SPECIFICATION forming part of Letters Patent No. 255,506, dated March28, 1882. Application filed January 19,*1882. (No model.)

To all whom it may concern:

Be it known that I, GEORGE F. HOEEEER, a citizen of the United States,residing at Ghicago, in the county of Cook and State of Illinois, haveinvented a new and useful Bottle- Stopper Fastener, (which has not beenpatented to myself or to others with my consentv combination of thespool, the'stopper, piston,

and the lever that the stopper may always be drawn squarely up into anduniformly expanded within the neck of the bottle, so as accurately andtightly to close the same; to which end it consists in the combination,with a shouldered tapering centrally perforated spool, of abarrel-shaped hollow perforated elastic stopper mounted upon the stem ofa piston, and compressed and expanded within the throat of the bottle,between the foot of said spool and the button of the stem of saidpiston, by a one-armed circular lever pivoted within the slotted head ofsaid piston.

In the drawings, Figure 1 indicates a central, vertical section of theshouldered tapering spool, made of wood or other suitable materialhaving a central perforation, a. b, and being concaved at both ends.Fig. 2 indicates a central vertical section of the piston, made of woodor other suitable material. The upper portion ot' the shank e c has aslot, d d, perpendicular to the perforation ff, passing horizontallythrough the head of said shank, and the stem gg has atits extremity aconcaved coneshaped button, c. Fig. 3 indicates the one armed circularlever W, made of malleable iron or other suitable metal, the perforationm near the circumference of the circle being at such a distance from thearm R of said lever that when said arm is forced down and rests upon theplate the pivot of the piston is on the center, and when the arm isforced upward said pivot is thrown off the center. Fig. 4 indicates acentral vertical section of the barrelshaped hollow stopperrX, made ofrubber or other elastic substance, having a central perforation, u, ateach end. Fig. 5 indicates a circular concaved plate, made of zinc orother suitable metal, having a central perforation, p, and is used forthe purpose of protectingV the wooden spool against the pressure o f thelever. If the spoolbe made of metal or of any other substance equallyhard, this plate becomes unnecessary. Fig. 6 indicates a centralvertical section ot' the fastener, showing all the parts as they appeartogether in position in the fastener when unlocked. Fig. 7 indicates thefastener constructed of the parts aforesaid, and as the same appearswhen locked. Fig.8 indicates a bottle closed by devices embodying myinvention.

The fasteneris constructed as follows: Mount the stopper upon the stemof the piston by forcing the same over the button c. Then insert theshank of the piston up into the perforation of the spool, and havingslipped the metal plate over the head of said shank, with its convexedside resting on the concaved surface of said spool, pivot the lever inthe head of said piston by driving a pin through the perforatlons f fofsaid head andmof said lever.

The devices may be operated to lock the stopper by inserting thefastener into the throat of the bottle until it rests with its shoulderupon the mouth of the vessel,and then forcing the arm of the lever downupon the plate. To

unlock the stopper, release the leverby forcing" shape or the irregularlength of the heads of IOO ble-shouldered stem g g, and button c, thepiu or axis passage ff, stem with couoaved shank having a horizontalpiuoraxis passage, button c, the one-armed perforated circular' ff, anda vertical slot7 d d, substantially as lever W, the circular eoneavedperforated shown and described. metal plate, and the barrelshaped hollowper- 5 3.
